Description
Technical Field
[0001] The utility model relates to the technical field of transformer devices, in particular to a complete set of power frequency non-partial discharge test transformer devices. Background Art
[0002] When partial discharge occurs inside power equipment, it is accompanied by impact vibration and electric sparks. These discharges will corrode the insulation, eventually leading to insulation failure and insulation accidents. The partial discharge test of switchgear insulation parts can effectively detect insulation defects such as bubbles and cracks inside the insulation parts that are difficult to detect in conventional withstand voltage tests. By carrying out relevant inspections, the quality level of internal insulation parts can be improved and the probability of insulation failure of internal equipment can be reduced.
[0003] When using the non-partial discharge test transformer, it needs to be connected to the external connecting wire, and the external connecting wire is sometimes long. After the test is completed, the external connecting wire needs to be stored for the next use. The existing non-partial discharge test transformer generally lacks a device for storing the external connecting wire, which easily leads to the external connecting wire being messy, thereby increasing the workload for the next use.
